Abstract

The invention discloses a special clamp used for machining an automobile clutch gland and a machining technique which is characterized in that a phenomenon that turning precision is lost because of elastic deformation of a workpiece after the clamp unclamps the workpiece is avoided through secondary depressurization tensioning, so that the turning precision is improved. Meanwhile, the invention discloses a principle of the special camp for machining the automobile clutch gland and a hydraulic principle which cooperates with the special clamp to realize a depressurization function.

Description

Automobile clutch cover blood pressure lowering turning process
Technical field
The high accuracy processing turning of the thin wall profile Complex Parts such as automobile clutch cover.
Background technology
The processing method of domestic automobile Clutch cover has two kinds at present.
One is by horizontal lathe artificial centering excircle of workpiece precision, and then hand-operated clamping workpiece starts turning, this adds Work mode easily makes workpiece deform, and working (machining) efficiency is low.
One is to use special pneumatic or hydraulically operated fixture, and this kind of fixture makes special fixture according to the shape of workpiece, this Fixture work efficiency is high, but due to during disposable clamping workpiece be deformed, after completing turning in this case, car Having cut fixture once to loosen, workpiece will cause workpiece to deform because of release clamping force, and the trueness error after turning is at 0.3mm Above.
Summary of the invention
This blood pressure lowering fixture is the thin-walled profile according to automobile clutch cover and the special fixture of complex-shaped feature design, Having quickly location, load and unload the convenient advantage of part, cardinal principle is: first with the alignment pin location workpiece of fixture, high voltage power leads to Crossing drag hook tension workpiece, now excircle of workpiece and end face can produce certain elastic deformation, make work under high pressure tightening force effect Part imposed deformation, to the flat position of alignment pin torr, at this moment carries out turning for the first time.
After turning completes for the first time, HYDRAULIC CONTROL SYSTEM hydraulic valve makes the clamping force of fixture be become low pressure by high pressure, draws The pulling force of hook tension workpiece diminishes, and at this moment workpiece returns to normal condition owing to the deformation of material rebounds.Alignment pin still can be right Workpiece positions, and it act as during low pressure turning preventing workpiece from rotating, and workpiece carries out second in the case of the amount of being badly deformed disappears Secondary turning, this fixture blood pressure lowering processing method can make workpiece accuracy control within 0.1mm, and traditional diamond-making technique workpiece accuracy exists More than 0.3mm.
Accompanying drawing explanation
Fig. 1 is that the present invention processes Clutch cover special fixture, and alignment pin 1 rotates drag hook 2 workpiece 3.
Fig. 2 present invention provides the hydraulic schematic diagram of blood pressure lowering, Superimposed relief valve 1 solenoid directional control valve 2 solenoid directional control valve 3 times Turn oil cylinder 4.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further details.
As Fig. 1 Fig. 2 show automobile clutch cover fixture and hydraulic schematic diagram, special fixture put into by workpiece 3, location Pin 2 positions the positioning reference holes on workpiece 3, rotates drag hook 2 half-twist workpiece pressing.
For the first time during tension workpiece, solenoid directional control valve 3 work of Hydraulic Station is strained for high pressure, pressure according to thickness of workpiece with Deflection regulation system pressure, high pressure tension workpiece makes workpiece 3 straightening coincide with special fixture.
Blood pressure lowering for the second time is strained, and when solenoid directional control valve 2 is energized, system pressure passes through Superimposed relief valve 1 control system pressure Reduce, low pressure tension workpiece, because the deflection of workpiece 3 has been corrected by high pressure, after being converted to low pressure, discharge deflection, this Time the cylindrical of turner 2, end face etc., turning rotates drag hook 2 and loosens workpiece half-twist and be easy to take out workpiece 3, workpiece after completing 3 machining accuracies can be good at controlling.Turning accuracy cylindrical is within 0.1mm, and face height is within 0.1mm.

Claims (3)

1. automobile clutch cover blood pressure lowering turning process is characterized in that realizing automobile clutch cover elder generation high pressure tension workpiece again Be converted to low pressure tension workpiece, eliminate a kind of processing technique of deflection.
2. automobile clutch cover blood pressure lowering turning process is characterized in that a kind of exclusive clamps for automobile clutch cover processing Tool.
The most according to claim 1, automobile clutch cover blood pressure lowering turning process is characterized in that for automobile clutch cover A kind of hydraulic system realizing blood pressure lowering of processing.
